WALL-PAPER-PASTING MACHINE.

Application led July 19, 1915.

To all lwhom t may concern:

Be it known that I, FREDERICK W. KRAFFT, a citizen of the United States, residing at Berkeley, in the county of Alameda, State of California, have invented a new and useful Wall-Paper-Pasting Machine, of which the following is a specification.

This invention has reference generally to improvements in that class of inventions known as coating machines and more particularly relates to a wall paper pasting machine. l As its object, the invention contemplates the provision'of a machine of the above mentioned character designed for automatically applying paste to a piece of wall paper or the like and embodies generally supporting means on which is mounted the pasting means, paper holding means and the paper guiding means while operably arranged above such means and cooperating therewith is a means for engaging and drawing the paper from the holding means, beneath the guiding means and thence over the pasting means so that the paste will be applied to one face of the paper.

The improvements in the details and arrangement of parts will be apparent from an inspection of the accompanying drawings, in connection with the specic description hereinafter contained, and lwherein the preferred embodiment of the invention is disclosed for the purpose of imparting a full understanding of the invention.

The invention is clearly illustrated in the accompanying drawings, in which:

Figure 1 is a perspective view of themachine,

Fig. 2`is a fragmentary side elevational detail of thevmain frame, partly in section and wherein the dotted lines indicate the position 'assumed by the paper clamping means when passing over the paste roll,

Fig. 3 is a 4transverse sectional detail through the upper lay of the belt with the clamping meansmounted thereon and shown in elevation, and

Fig. Llis a detail of the clamping means.

Similar characters of referencey are employed in all of the above described views, to indicate corresponding parts.

A paste container A, is set on legsB, in which is a revolving roller C, which has attached toy it a crank D by the axle E. A movable frame F is placedabove this, held up by standards G, which fit against the y Specieaton of Letters Patent.

ends of paste container A. The standards rest upon projections at the bottom of container A. They are also pivoted on the aXle E so that the frame may be brought down against the legs B, which is shown by dotted lines in Fig. 1. The top of the frame F is on a level with the folding trestle, Fig. l, to support'pasteboards 6'; a space is left between the boards for the belt H. The pasteboards o', as will be understood, serve as supports for the sheets of wall paper after the same has had an adhesive applied to one side thereof, thus keeping the same iiat and preventing wrinkling or creasing.

Av spindle I having a space around its center to fit the belt H is bracketed in the end of the frame F. The spindle is for the paper to pass around.

A wheel J is placed at the other end of the boards and between them. The aXle of J is attached to brackets slipped over the corner of each board. Belt H passes between the boards, around spindle I and wheel J,

completing its circuit under the table. The

spindle I is connected by shaft K and gear wheels L to the axle E by which means the belt is operated.

The clamp M consists of a plate m1 to which is swingably connected a clamping wire loop mi., while also swingably connected to the plate 'm1 is the narrow depending neck of the collar a. Collar a is made of flat metal through which belt H is enabled to slide when the collar lies flat on the belt, but its edges gras-p or tighten on the belt when turned edgewise. It 'is intended that the part of the belt under the table shall always move from left to right as one faces the machine. The collar a has anarrow neck the purpose of which is to pass through the slots in the belt supports as shown and described.

The spring b is attached to the inside of the back plate of theclamp M, the arm `of same is attached to front plate drawing it shut. The tension of the spring b is so placed that if one opens the clamp wide the spring b vpasses its center and inust be brought back over the center to close the clamp.

Suspended from the frame Fare belt supports N, N1, N2; each one is composed of two pieces which do not meet in the center under the belt but leave a slot or opening between them, which is for the passage of the neck of the clamp-,NL

A swinging frame O is hung in the frame F'provided with a slot to leave a free passage for belt H. The slot is open at the bottom so the frame O may be lifted clear of the belt H. The lower side of frame O is suspended near the edge of covered part of paste container A1, just above the paste roller C.

Pivoted in the frame F is a rod P from which extend hangers c, c. The ends of these hangers are so bent as to support frame O. The curved bars cl, cl rest upon frame O to raise the hangers, o, c', when the frame O is lifted.

This movement lowers belt support N1 which extends from rod P. In normal position the belt support N1 lifts the belt above the support N; thus the neck of clamp M passes through N, but is stopped 'by support N1. When the frame O is lifted, the support N1 is brought down and the clamp M can be drawn through N1 and over the paste roller C.

The guide S of the rotary cutter frame T is placed at the lower edge of the frame O, and is in two parts. The frame 'I of the cutter U is made of a suitable bar to slide on the guide S and is long enough to pass from one part of the guide to the other across the slot in frame O. Operatively connected to the bar is the cutter wheel U which of course is disposed beneath the guide while carried with one end of the bar -is the operating rod Y preferably depending from the bar as shown in the foreground of Fig. l. The cutter wheel U operates between the covered part A1 and the frame O against the paste roller C. The paper is cu't where the wheel U comes in contact with the covered part A1. The holder Q is placed across the covered part A1. It is composed of a spring rod g hinged on one side of A1, to which is attached a folded piece of metal e whose lower outer edge rests upon the covered part A1, so it will turn on the rod for the purpose of drawing or stretching the p'aper. The spring rod g lifts the holder so the paper may be slipped under it; a latch is attached to fasten it down.

An apron V is hinged to the lower edge of the covered part A1 by one of its edges and is composed of two' fiat surfaces hinged. The other edge is bent and hooked over a rod attached to the upper edge of A1, from whence it may be removed and drawn up and placed over the paste roller.

The paper rack R placed upon the apron V is a spring rod fastened to one edge of apron V, the spring of the rod raising the rod up. A lug on the opposite side holds the end of the rod R down.

The folding trestle, Fig. 3, is composed of two pair of legs W, WV and a bar Z. One pair of legs is bolted to an end of the bar Z, the other pair is bolted together so the bar Z will slip between them; a slot in the bar Z fits over the bolt between this pair of legs. This arrangement permits the removing and inserting of belt H.

Folding braces X, X are attached on .the inside of the legs WV on each side, extending from one pair to the other. Braces to spread the legs of each pair are also shown. The whole is so made that it may be folded in `a compactJ package.

The operating of the machine is done in the following manner:

The trestle, Fig. 3, is set up; the folded machine is set in the proper place; the apron V is brought down and fastened in place; the belt is brought up and placed around the bar of the trestle Z; the frame F with its appurtenances is raised up and the paste boards placed; the belt is put in position; the paper rack R and holder Q, are unfastened; -a roll of paper is partly unrolled and placed upon the paper rack and under the holder; these are then fastened down,

leaving the end of the paper extending above the holder. The clamp being open, is drawn by the belt until it passes the belt support N, when it is in position to grasp the paper if it is closed. The frame O is raised up, lowering the support N1 as described, when the closed clamp may be drawn forward by means of the belt H over the 'pasting means around the spindle I and V.along on top of the paste boards, drawing the paper with it; the frame O being let down as soon as the clamp M has passed it which engages the paper and the pasting means. When the paper has been drawn past the pasting means the right. length, it is cut Off by the operation of the rotary cutter.

I am aware that pasting machines have been invented where the paper is drawn over paste rollers. I, therefore, do not claim that process. What I do claim as new and desire to secure by Letters Patent is;

l. In an adhesive applying device, the combination with a container having an adhesive delivering roller therein, of a frame hingedly mounted on said container, a second frame, a roll holder, a strip conveyer, and means for simultaneously imparting motion to said delivering roller andl said conveyer to cause said strip to be drawn over said roller to receive an adhesive compost tion.
